Kelly Brown continues to battle a once-debilitating stammer, but the Scotland captain has no problems barking orders to team-mates on the field.

"I find I don't stammer when I shout, and I tend to shout quite a lot on the pitch," Brown said. "I know it's part of me and all of the players know it's something I'm working on."

The Saracens flanker routinely has undertaken daily breathing exercises to get on top of the problem since hitting rock bottom ahead of the 2010 Six Nations.

"I was asked if I could do an interview right at the start, and it was so bad that I actually phoned and asked if that interview could never be shown," Brown said. "That was really the final straw, I said, 'right I need to do something about this'. I never wanted my stammer to be an excuse for why I couldn't do something."

Brown now barely has a problem, and he certainly had no trouble making himself understood at the Six Nations launch in London on Wednesday.

"It's something I will continue to work on and I work on every single day," Brown said. "I get up in the morning and I do my breathing exercises. But I know if I can do that and I can put in the work, I know that most of the time I'll be in control of my speech."

Scotland coach Scott Johnson said that Brown was an inspiration.

"I've been asked what inspires me, and it's people who overcome some kind of adversity," the Australian said. "This kid's an inspiration, to do that. It's not a massive adversity compared to others, granted, but to stand up in front of people every day and for him to speak, that inspires me. It's a good thing."
